Thermal Analysis of the Factors Influencing Junction Temperature of LED Panel Sources

Limiting junction temperature Tj and maintaining its low value is crucial for the lifetime and reliability of semi-conductive light sources. Obtaining the lowest possible temperature of Tj is especially important in the case of LED panels, where in a short distance there are many light sources installed, between which there occurs mutual thermal coupling. The article presents results of simulation studies connected with the influence of construction and ambient factors that influence the value of junction temperature of exemplary LED panel sources. The influence of radiator’s construction, printed circuit boards, as well as the influence of ambient factors, such as ambient temperature Ta and air flow velocity v were subjected to the analysis. Numerical calculations were done in the FloEFD software of the Mentor Graphics company, which is based on computational fluid dynamics (CFD). For construction of the LED thermal panel model the optical efficiency ηo and real thermal resistance Rthj-c were determined in a laboratory for the applied light sources.

Optimal energy supply in different age groups of critically ill children on mechanical ventilation

Objective: To analyze the resting energy expenditure and optimal energy supply in different age groups of critically ill children on mechanical ventilation in pediatric intensive care unit (PICU). Methods: Patients on mechanical ventilation hospitalized in PICU of Beijing Children's Hospital from March 2015 to March 2016 were enrolled prospectively. Resting energy expenditure of patients was calculated by US Med Graphic company critical care management (CCM) energy metabolism test system after mechanical ventilation. Patients were divided into three groups:<3 years, 3-10 years, and >10 years. The relationship between the measured and predictive resting energy expenditure was analyzed with correlation analysis; while the metabolism status and the optimal energy supply in different age groups were analyzed with chi square test and variance analysis. Results: A total of 102 patients were enrolled, the measured resting energy expenditure all correlated with predictive resting energy expenditure in different age groups (<3 years (r=0.3, P=0.0) ; 3~10 years (r=0.6, P=0.0) ;>10 years (r=0.5, P=0.0) ) . A total of 40 cases in < 3 years group, including: 14 cases of low metabolism (35%), 14 cases of normal metabolism (35%), and 12 cases of high metabolism (30%); 45 cases in 3-10 years group, including: 22 cases of low metabolism (49%), 19 cases of normal metabolism (42%), 4 cases of high metabolism (9%); 17 cases in>10 years group, including: 12 cases of low metabolism (71%), 4 cases of normal metabolism (23%), 1 case of high metabolism (6%). Metabolism status showed significant differences between different age groups (χ(2)=11.30, P<0.01, r=-0.01). Infants had higher metabolic status, which lessened with aging. The total average actual energy requirement was (210±84) kJ/ (kg⋅d) . There were significant differences in actual energy requirement between age groups (F=46.57, P<0.001), with (277±77) kJ/ (kg⋅d) in<3 years group, (184±53) kJ/ (kg⋅d) in 3-10 years group, and (120±30) kJ/ (kg⋅d) in>10 years group. Conclusion: The resting energy metabolism of the critically ill children on mechanical ventilation is negatively related to the age. The actual energy requirement should be calculated according to different ages.

Assessment of energy metabolism and nutritional supply in children with mechanical ventilation

To determine the resting energy expenditure on mechanical ventilation in pediatric intensive care unit (PICU) by indirect calorimetry, and analyze the distribution of metabolic states. The nutrition supply was assessed according to the resting energy expenditure. An observational study which was held in PICU of Beijing Children's Hospital from November 2013 to April 2014. Critically ill children with mechanical ventilation were enrolled in this study. The inclusion criteria included the following: (1) pediatric critical illness score < 90, or meet the United States PICU admission criteria; (2) age > 29 days, < 18 years old; (3) time of mechanical ventilation > 24 hours; (4) volume of mechanical ventilation > 60 ml. Resting energy expenditure was determined by US Med Graphic Company CCM/D energy metabolism test system. Predictive resting energy expenditure was calculated for each subject with age-appropriate equation (Schofield-HTWT). According to the actual energy intake records and required energy intake (10% higher than the measured value) to define the nutritional status. The selected subjects were grouped according to gender, age, types of disease and nutritional status, and compared the metabolic status and nutritional supply of different groups. Sixty-eight children were enrolled in this study, 46 were boys and 22 were girls, including 25 cases of pneumonia with respiratory failure, 23 cases of central nervous system diseases complicated with respiratory failure and 20 cases of postoperative tracheal intubation. The ratio of boys and girls was 2:1. The results showed 36 patients in a low metabolic state, accounting for 53%, 23 patients in a high metabolic state, accounting for 34% and 9 patients (13%) in the metabolism of the normal state. In the male children, 12 cases (26%) were in the high metabolism and 26 cases (57%) were in the low metabolism, and 8 cases (17%) were in the normal metabolism. In the female children, 11 cases (50%) were classified into high metabolism; 10 cases (45%) into low metabolism and 1 case (5%) was classified into normal metabolism. There was no significant difference in the distribution of metabolic status among different gender(χ(2) = 4.176, P = 0.095). In terms of ages, 15 cases (63%) were mainly in high metabolism in the patients at age < 3 years, 19 and 11 patients in 3-9 and 10-18 years age group respectively are mostly in low metabolism. As to the diseases, pneumonia complicated with respiratory failure and central nervous system diseases complicated with respiratory failure with mechanical ventilation (respectively 15 cases (60%) and 12 cases (52%)) were in low metabolism mainly; 11 cases of postoperative tracheal intubation were in high metabolism states, accounting for 55%. The distribution of metabolic status in different age and clinical diagnosis had significant difference. Thirty-one patients had normal nutrients supply, accounting for 46%, 37 patients had inappropriate nutrition supply, accounting for 54%, including insufficient supplies of nutrients in 22 cases, accounting for 32%, excessive supplies of nutrients were seen in 15 cases(22%). There were no statistically significant differences among the different types of diseases. There are differences in the metabolic state of the mechanical ventilation in critically ill patients, mainly in low metabolic state. The age and types of diseases can affect the metabolic status of patients. Empirical nutritional support is not applicable to patients.

Six Sigma: A Key Driver for Process Improvement

Six Sigma is a one of the most common used programs in production companies for reduce cost, improve productivity and provide a basis for goals improvement which leads to competitive advantage. Understanding the key Six Sigma factors (Total Quality Management, strong customer focus, data analysis tools, financial results and project management) allows organizations to better support their strategic directions focused on improving customer requirements through the improving of own business systems and operational performances. In this paper will be described a Six Sigma approach and presented results of the empiric research conducted in Croatian graphic companies. All findings of this empiric research will provide better understanding of Six Sigma benefits and graphic companies, but production companies will be able to guide business and production processes in right directions with minimizing inputs, maximizing outputs and satisfy owners, employees and customers.

Achieving a Competitive Advantage by SCM

The supply chain concept is theorized from the formation of a value chain network consisting of individual functional entities committed to provide resources and information to achieve the objectives of efficient management of suppliers as well as the flow of parts. The understanding and practicing of supply chain management have become an essential prerequisite for staying competitive in the global race and for enhancing profitability. In this paper, the role of SCM (Supply Chain Management) will be described and the results of the empiric research conducted in Croatian graphic companies will be presented. Research framework is based on a theoretical framework and includes two main dimensions: SCM practices(strategic supplier, partnership, customer relationship, level of information sharing and quality of information sharing, postponement) and competitive advantage (price and cost, quality, delivery dependability, product innovation, time to market). All findings of this empiric research will provide better understanding of SCM benefits for graphic, and production companies as well, which will be able to achieve competitive advantage through the tactical planning and control, but also with respect to strategic intent. Also, results of the empirical research provide justification of a framework that identifies five key dimensions of SCM practices and describe the relationship among SCM practices and competitive advantage observed through the five dimensions.

Las empresas metalgráficas en Galicia (1890–1936)

This paper aims to analyze the role of metal graphic companies in Galicia. Metal graphic is an activity that has gone virtually unnoticed in economic history, despite having played a key role in the development and competitiveness of the canned fish sector, which for many years was the basis of the industrialization of Galicia. In fact, considering the metal graphic companies as a mere auxiliary activity of the canning industry has tended to conceal their characteristics as companies specialising in the production of modern packaging. This is a key factor without which it is impossible to understand how even today heirs to these companies established in the early part of the century still occupy a leading position in the packaging sector. The factors that led to the appearance of metallographic companies, their concentration in Vigo, and the factors which influenced their specialization throughout the various stages until the onset of the civil war are analyzed.

Creating Accessible Science Museums With User-Activated Environmental Audio Beacons (Ping!)

In 2003, Touch Graphics Company carried out research on a new invention that promises to improve accessibility to science museums for visitors who are visually impaired. The system, nicknamed Ping!, allows users to navigate an exhibit area, listen to audio descriptions, and interact with exhibits using a cell phone–based interface. The system relies on computer telephony, and it incorporates a network of wireless environmental audio beacons that can be triggered by users wishing to travel to destinations they choose. User testing indicates that the system is effective, both as a way-finding tool and as a means of providing accessible information on museum content. Follow-up development projects will determine if this approach can be successfully implemented in other settings and for other user populations.

The project-management approach in the “systematic management” of innovative start-up firms

This paper presents the principal results obtained by applying the project- management approach to strategic planning and operations management of innovative start-up firms' key activities. This approach is used to implement Drucker's view of entrepreneurship as a systematic discipline and his recommendation that innovation be treated using his principle of systematic innovation. As is well known, the management of growth in an innovative start-up firm is a difficult problem facing that organization. During this particular stage of the firm's development, many interdependent activities need to be performed under the conditions of uncertainty and limited resources. In these cases, flexibility and contingency planning are necessary. The fact that there exists no generally accepted approach that an entrepreneur can utilize, however, results in chaotic situations in many such enterprises. The start-up firm cannot utilize the formalized management systems and procedures available and useful in large firms. In addition, a disorganized, chaotic, random management-decision process will seldom provide desirable results in such firms. Viewing the firm as a project to be managed with specific tasks, activities, precedence relations, durations, and milestones presents an opportunity to utilize project-management techniques, including the critical-path method (CPM). Recent research has demonstrated that project-management methodology and its computer- software applications are applicable to small, innovative start-up firms. By utilizing a microcomputer, one can analyze any start-up business for flaws in management or organization and can chart a more productive path for achieving the firm's strategic goals. Project management using computers is not new: it has been used for years for major aerospace, utility, and construction projects. Only recently, however, have microcomputers and software become inexpensive enough to allow small firms to utilize this approach. The project-management approach collects information about a start-up firm, including all of its planned activities consistent with its evolving business plan, and then utilizes a microcomputer and inexpensive, readily available project-management software to process the information collected. Among the outputs are a “GANTT chart,” which indicates when the various activities should begin and end; a “Job Report,” which provides the earliest and latest possible deadlines for starting and ending each activity; and a “Milestone Report,” which indicates when each key event is to be accomplished according to the strategic business plan. These status reports are extremely valuable to the CEO and to the management team as the firm is kept on course according to its strategic plan. This methodology has been applied to 20 innovative start-up firms in northern California, including a computer graphics company, a semiconductor-equipment manufacturer, and firms that develop software for professional athletes, educators, ophthalmologists, and radio-station managers. In addition, the project-management approach has been applied to plan and schedule Stanford University's current centennial fund-raising campaign. Results indicate that the CEO and the entire management team are able to plan, schedule, and control the innovative start-up firm's multiplicity of activities in a systematic way. The firm is also able to modify its strategic plan based on a review of its updated status reports and to modify its operations plans accordingly. Current research is under way to develop similar systematic methods for managing innovations in large organizations.

Unique Methods of Visual Presentation With Respect to Accident Reconstruction

Obviously, communication is one of the most important aspects of forensic engineering. Communication is certainly important between both the engineer and the lawyer as well as the engineer and the jury. Of course, communication involves not only sending a message to someone but also making sure that the message is understood by the person receiving it. Speaking and sending letters are two methods of sending a message. However, perhaps a more direct form of communication is visual. The old adage 'a picture is worth a thousand words' has been proven many, many times. Therefore, this discussion deals with two very specific methods of achieving communication through visual presentation. First of all, understand that these two methods are directed primarily toward accident reconstruction. For purposes of illustration, an automobile accident will be used as an example; however, these methods can be applied to other types of accidents as well. The first method, one involving aerial photography, is currently under development. The other method, which is primarily graphic, is already developed and available through several graphic companies or individuals.
